For the July R lab, we’ll be working with a slightly modified version of the strath/nodobo dataset, a dataset gathered by researchers at the university of Strathclyde who used Nodobo (a suite of social sensor software for Android phones) to study mobile phone usage, . Download the modified dataset here. For those interested, there are also a wide variety of other wireless data related datasets available through CRAWDAD (A Community Resource for Archiving Wireless Data At Dartmouth).
The strath/nodobo dataset is a good dataset for trying out social network analysis (SNA), which uses graph theory to analyze the structure of social connections. There are many SNA libraries available in R or Python. For this lab we’ll be focusing on iGraph, which is available in both R and Python.
To get started with R and igraph, you can try out this very simple, but typical, R script.
